Cheers for the reply and explanation.. I did a search for "G10 JPEG + RAW" and couldn't find the answer I was looking for.
No doubt this has been said many times then....
I thought the point of having a RAW+JPEG on the camera, would be so you could hook it up to say the TV/PS3 and view the files, without having to convert the RAW files to JPEG. Handy if you were on holiday and wanted to review on a TV.
Seems pretty pointless having a setting on the camera for JPEG+RAW, especially as it seems to save the RAW file twice? taking up twice the room needed.
All in all, I'm loving this camera! And its my first camera, in well over 10 years, I don't count camera phones!
